Abstract:
Taking corn straw and sawdust as the test materials，six different proportions of corn straw and sawdust formulas were set up by single factor randomized block experimental design.The effects of different formula substrates on the mycelial growth rate，extracellular enzyme activity，fruiting body morphology，biological efficiency and input-output ratio of Lentinula edodes were studied，in order to provide reference for the decay cultivation of Lentinula edodes.The results showed that with the increase of corn straw content in the substrate，the dry matter mass and carbon-nitrogen ratio per unit volume of the substrate gradually decreased，the mycelial growth gradually became weak and slow，and the extracellular enzyme activity，biological efficiency and input-output ratio showed a trend of increasing first and then decreasing.In conclusion,the addition of corn straw to cultivate Lentinula edodes was not likely to exceed 48%.When the addition amount of corn straw was 16% (sawdust 64%，corn straw 16%，bran 18%，gypsum powder 1%，sucrose1%)，the biological efficiency and input-output ratio were the highest，reaching 77.30% and 1∶1.44，respectively.
